$1/2 AKo first hand - 4b/c/f?

$1/2 literal first hand. Wednesday day game.

UTG +2 $12, UTG +3 call, UTG +4 (main V) goes $40. H came in behind the button looks down at AKo. Don’t know UTG +2 or +3. Main V is very loose, sticky, aggro, all kinds of active. I’ve played with him a bit but I don’t know what he thinks of me. He also has different modes. Can be straight maniac but doesn’t always play that way. Usually running hot or cold sets him off. It’s early in the day so my best guess is he isn’t tilted yet. H bought in for $300 (max), V covers slightly. Most other players are around $300 as well.

H?
